Abstract

The invention discloses a detection method for the true density of iron-containing powder, belonging to the technical field of detection of the basic performance of metallurgical iron-containing powder. The detection method comprises the following concrete steps: step 1, pretreatment: drying to-be-detected iron-containing powder at 105 + / - 5 DEG C; step 2, removal of bubbles: heating the iron-containing powder in a water bath to remove bubbles in the iron-containing powder; and step 3, detection and calculation of true density: adding the iron-containing powder into a detection bottle, fixing a volume by using a burette and calculating the true density. According to the invention, the whole process is controlled, and bubble removal of the iron-containing powder is carried out in a beaker, so the volume of the detection bottle is prevented from influence by heat at high temperature; the burette is employed for volume fixation, so weighing frequency and errors are reduced; and thus, the true density of the iron-containing powder is accurately detected.

Description

technical field [0001] The invention relates to the technical field of basic performance detection of metallurgical iron-containing powders, and more specifically relates to a method for detecting the true density of iron-containing powders. Background technique [0002] The pelletizing method is a method of iron ore powder agglomeration, which is to mix various iron concentrates or finely ground natural ores with water and pellet binders to make green pellets, and then roast them at high or low temperatures to form pellets. mine. Pellets have the advantages of good strength, uniform particle size, regular shape, high iron content, good reducibility, etc., and have become an indispensable high-quality metallurgical charge in blast furnace smelting. Pellets can increase production and save coke, improve ironmaking technical and economic indicators, reduce pig iron costs, and improve economic benefits. With the increasingly stringent requirements of modern blast furnace iron...
